From Russia with Love: POHMELFS – A New Distributed Storage Solution
There is a new file distributed file system in the staging area of the 2.6.30 kernel called POHMELFS. Sporting better performance than classic NFS, it's definitely worth a look.
Ramdisks – Now We Are Talking Hyperspace!
Ramdisks can offer a level of performance that is simply amazing. More than just a tool for benchmarking, there are new devices that utilize ramdisks for a bit of the ultra-performance.
FS-Cache & CacheFS: Caching for Network File Systems
FS-Cache along with CacheFS is now in the 2.6.30 kernel and can be used for local caching of AFS and NFS.
SquashFS: Not Just for Embedded Systems
Who knew that compression could be so useful in file systems? SquashFS, typically used for embedded systems, can be a great fit for laptops, desktops and, yes, even servers.
NILFS: A File System to Make SSDs Scream
The 2.6.30 kernel is chock full of next-gen file systems. One such example is NILFS, a new log-structured file system that dramatically improves write performance.
FS_scan: Getting Detailed with Your Data
Need details on your file system's data? FS_scan allows you dig deep into your storage, giving you the ability to perform trend analysis on the results.
How Old is that Data on the Hard Drive?
The vast of amount of data being stored in this day and age, naturally leads to files sitting unused for longer and longer periods of time. A new app, agedu, can quickly tell you what data on your filesystem is lying fallow.
Linux Don’t Need No Stinkin’ ZFS: BTRFS Intro & Benchmarks
ZFS may be locked into the Solaris operating system but "Butter FS" is on the horizon and it's boasting more features and better performance.
ext4 File System: Introduction and Benchmarks
Destined to become the default file system for the more popular Linux distributions, ext4 is out of experimental mode and gearing up for production environments. Here's what you need to know.
ZFS on FUSE
Although its features and terminology may seem strange if you're used to more traditional Linux filesystems, ZFS offers a great deal of flexibility.
Solving Common Administration Problems with ZFS
One of the most interesting features in Solaris is its ZFS filesystem. Read on for a quick guide to ZFS administration.
Thin Clients in the Holy Land
By
Here's an idea: With a network of Nivos, a few extra monitors, keyboards, and a modest PC to act as a server, a whole classroom of kids can work on a whole slew of software.
Getting Ready for Samba4
Samba Team member Andrew Bartlett explores the world of Samba4, its development status, what you can (and can't) do with Samba4, and -- most importantly-- when you can expect to start using Samba4 in a production environment.
Inside Intel
By
When you hear "Intel Inside," you're likely to think of hardware, particularly processor technology, chip sets, motherboards, servers, and desktops. But the company has a "softer" side as well — for a number of years, Intel has been building up its software divisions, creating tools that target everything from performance libraries, to XML, to mobility.
Parallel Platters: File Systems for HPC Clusters Part Three
In the last installment of our Parallel Platters series, Jeff Layton looks at the next generation of parallel file systems: Object Based File Systems.
A Tour of the Linux File System
Take a tour of the Linux filesystem. Drive down /bin Street, cruise over to /usr Lane, and buy some souvenirs over in /dev Drive.
Storage Solutions That Enable Semiconductor Design For Manufactuing (DFM)
Today’s EDA tools are straining existing computing and storage resources and require a storage solution designed for very high performance and massive storage needs. This paper is for chip vendors, EDA tool vendors, mask merchants, and foundries seeking in excess of 1GB/s sustained throughput and storage capacities of 100TB or more, with superior read/write performance, reliability, and scalability. Semiconductor pre-production processes, driven by shrinking process technologies, require the use of high-performance cluster computing, support for massive file sizes, and the ability to sustain very high performance I/O with faultless streaming during photomask preparation and production. This paper outlines how DataDirect Networks’ storage solution, provides an ideal solution for computing environments that need to keep pace with the exponential increases in data size, complexity, and compute requirements brought about by ever-shrinking node sizes.
Implementing Cost-Effective D2D Backup and Recovery with StoneFly’s Integrated IP SANs
